Try this.

Write half a page of anything you desire while maintaining a prose, poetic and rhythmic structure.

 

That is the easy bit. 

 

Now.....

Also try aligning vertically one word in it whenever it appears.

 

Still not hard enough.....

 

Now do that on every page.

 

Subhan'Allah, His name lines up nearly on nearly every page.

No literature can ever compare to his word.

 

 

11.31 Or do they Say: "He invented it!" Say: "Bring ten invented chapters like it, and call on whom you can besides God if you are truthful."
